Open a web browser and log in to the firewall. The default address is http://192.168.1.1. The username is: admin and the default password is: mono

1.) Click on ‘General Setup’ under ‘System’
2.) Type in a new password in both boxes. As a general rule of thumb you should you upper and lowercase characters as well as symbols.
3.) Select the time zone you are in.
4.) Click the ‘Save’ button.
After you click save the firewall will prompt you to log back in with the new password.

If you are going to access any devices on your local network via the Internet you need assign them static IP addresses. This is important if you’re going to log into your workstation remotely via a service like ‘Back To My Mac’, connect to a SlingBox remotely or play video games via a PC, Xbox360 or a PS3. This will become clear when we start configuring Port ‘Forwarding’. So let’s get started on assigning IP addresses to these devices. For this example we are going to assign a static IP to the workstation connected to the firewall. We will need to know the MAC address of the device, this is the physical address of the network interface. On some devices you will see a sticker which states the MAC address of the device, on others you will have to go into a configuration or information screen to gather that information. The MAC address will be in the following format ##:##:##:##:##:##, it will be a combination of numerals and characters. On a Mac you would click on the Apple logo on the menu-bar, go to ‘About This Mac’, ‘More Info..” and click on ‘Network’. You will see the different available network interfaces, click on the network interface in question and you will see the MAC address of the interface. So now that you have the needed information, lets proceed.
Also the static IPs have to be outside the range of IPs given out by the DHCP server. The default range is 100 – 199, keep that in mind.
1.) Click ‘DHCP server’ under the ‘Services’ section
2.) Click the ‘+’ symbol under the ‘Reservations’ section

1.) Enter the MAC address of the device you are adding
2.) Enter the IP address you would like to assign to the device. (i.e.. 192.168.1.200) Make sure the IP address falls within the range of your local network.
3.) Enter a description for the device you are adding a static mapping to and click save.
Repeat these steps for every device you need to add. Once you are done continue to the next section.

1.) You will notice your new reservations listed below.
2.) Click the ‘Apply changes’ button.
3.) If you are installing 1.3 version you will see the above error. This is a bug in that version, it will be fixed in the next revision.
**If you do get this error after clicking ‘Apply changes’, you need to reboot the firewall. To do that click ‘Reboot system’ under the ‘Diagnostics’ section. Once you do that the changes will take affect.

1.) Click on ‘NAT’ under Firewall
2.) Make sure ‘Inbound’ is selected
3.) Click the ‘+’ symbol

I am going to create a port forwarding rule as if I had a SlingBox on my local network. SlingBox uses TCP port 5001 to communicate with the Internet. So I am going to configure a rule that states and traffic coming in on the WAN port (Internet interface) on TCP port 5001 be forwarded to an IP address on my local network. These are the steps to achieve that:
1.) Interface: should point to WAN
2.) External address: should point to ‘interface address’
3.) Protocol: select the appropriate protocol from the drop down (i.e.. TCP)
4.) External port range: enter the port number in both boxes (i.e.. 5001)
5.) NAT IP: this would be the IP address of the device on your local network (i.e.. 192.168.1.200)
6.) Local port: this would be the same port number used in step 4 (i.e.. 5001)
7.) Description: enter a thorough description of the device and port number you are forwarding for future reference
8.) Click the checkbox: This will automatically create the firewall rule you will need at the same time.
9.) Click the ‘Save’ button
Repeat these steps if you have multiple ports you have to open for a device. Also repeat these steps if you have multiple devices to add.

Once you are finished adding all of you port forwards, you can click on the ‘Apply changes’ button and you are done

Xbox360 Live: UDP/TCP 3074
PS3: TCP 5223, UDP 3478. UDP 3479, UDP 3658 **Certain games may require additional port forward mappings, check with game vendor
SlingBox: TCP 5001
If you need information on ports for device not listed here, check with the manufacturers support web page. If you cannot find it there try Googling: firewall port forwarding for (then add your device and then hit the ‘Search’ button)

We are done with this segment of the tutorial. In the next installment we will discuss Dynamic DNS services and VPN Tunnels (IPsec Mobile, PPTP).
